| 1. A veterinary goniometer comprising:
a. an anchor platform having an upper leg mounting means thereon for affixing an animal upper leg to the anchor platform,
and wherein an animal upper leg affixed in the leg mounting means is oriented along an anchored leg axis;
b. a mobile platform adjacent the anchor platform, the mobile platform having a lower leg mounting means thereon for affixing
an animal lower leg to the mobile platform, the mobile platform being translatable in a testing direction oriented
(1) at least substantially perpendicular to the anchored leg axis, and
(2) at least substantially parallel to the goniometer base; the mobile platform also being pivotable about a pivot axis:
(3) oriented at least substantially parallel to the anchored leg axis; and
(4) spaced from the mobile platform;
c. a force transducer engaged between the anchor platform and mobile platform, the force transducer providing an indication
of the force required to translate the mobile platform with respect to the anchor platform;
d. a goniometer base:
i. affixed to the anchor platform, and
ii. about which the mobile platform is restrained to move, with the goniometer base always being spaced from the anchor platform
